These strings allow you to slide up and down the fretboard as quickly as you like due to the their being flatwound and light gauge. Also, there is no string noise between notes. As for tone, it is deep and full, not metallic and ringing. They are perfect in my estimation.

45 years of bass playing and I'm sure I've tried them all and when I say I'm Impressed I mean it .Good job Ernie! They're Flatwound Bass Strings. They don't have many "Features". You buy the guage you need and put them on your bass. Hopefully when you do you will like them as mauch as I do. As a long time user of D'Addario Chromes on my fretless basses I decided to give these a try due to all the good reviews of all the "Group" strings. (Thank You To All Those Who Submit Reviews).I recently put these on my backup fretless ( Ibanez SR 300 ) and was duly impressed.They are Brighter than the Daddy Chromes I've used for years and they will put you somewhere between the Jaco tone and the Pino tone. ( Bright But Not Brittle).They also feel slightly smoother than the DaddiesI like these strings so much that I just ordered a set of Group III to put on my "77 Musicman Stingray fretted bass that has only been strung with roundwounds or halfrounds for over 30 years. In a few words: Bass Strings Ain't Cheap !!! ----Read the reviews before you buy and hopefully you will find the best bang for the buck.

Wow, a big change for all you roundwounders out there... I slaped these babies on and fell in love with them. they have great clarity with nice big low end, but overall produce a very mellow sweet sound. They are VERY easy on the fingers, unless you play long or hard and you sweat... then these strings turn into sandpaper!
